我試圖在框圖中插入一個文本框，但是出了點問題。 讓我們先繪制箱線圖：

import pandas as pd

import matplotlib.pyplot as plt

import seaborn as sb

df_data = pd.read_hdf('data.h5', key=f'df_data')

##print(df_data)

fig, (ax1, ax2) = plt.subplots(1,

2,

gridspec_kw={'width_ratios': [3, 1]})

my_pal = {'PtP':'dodgerblue', 'T1':'salmon', 'T2':'salmon', 'E':'limegreen'}

sb.boxplot(data=df_data[['PtP', 'T1', 'T2']], ax=ax1, palette=my_pal)

sb.boxplot(data=df_data[['E']], ax=ax2, palette=my_pal)

posx = 1500

posy = 'T1'

##ax1.text(posx,

## posy,

## f'Average Impulse Interval: Over9000',

## bbox=dict(facecolor='wheat'))

ax1.set_ylim(0)

ax1.set_ylabel('Voltage / mV, Time / ns')

ax2.set_ylim(0)

ax2.set_ylabel('Energy / fJ')

fig.suptitle('Distribution')

plt.grid(axis='y')

plt.show()

現在，當我嘗試取消注釋時：

ax1.text(posx,

posy,

f'Average Impulse Interval: Over9000',

bbox=dict(facecolor='wheat'))

Matplotlib引發錯誤：

我嘗試用整數或浮點數替換'T1' ，但這無濟于事。

不相關似乎我需要在此帖子中添加更多文本。 不要因為我在這里輸入的廢話而分心。
